The wobbling-rolling action of the Yo-Zuri 3DB Deep Crank hunts fish utilizing the Patented Internal 3D Prism Finish or New Painted Finish, and Wave Motion Technology. The large round buoyant body and lip designs help you crank and bump over structure and eliminate snags. The “red” eyes are an indication of a distressed baitfish on which big fish key-in, creating a natural predatorial strike response.
